In a logistic regression a positive/negative beta tells you that the direction that variable works. Is there anything in the Random Forest variable importance measures that indicates the direction of the variable?

One possibility (without variable importance) would be to display partial dependence plots, which show you the connection between the variable and (one) predicted class. See partialPlot in randomForest package in R for more information.
You can also use the Partial prediction options in mlr http://mlr-org.github.io/mlr-tutorial/devel/html/partial_prediction/index.html
